Question
At the lowest energy level, α-helix of the polypeptide chain is stabilized
- By hydrogen bonds formed between the H of peptide N and the carbonyl O of the residue
- Disulfide bonds
- Non-polar bonds
- Ester bonds
Hint:
By hydrogen bonds
The correct answer is: By hydrogen bonds formed between the H of peptide N and the carbonyl O of the residue
- α-Helix and β-Pleated sheets are types of the secondary structure of the protein.
- They are shaped by hydrogen bonding between H of peptide N and the carbonyl O of the residue.
- So, the correct option is a.
